Filed July 6, 1962, Ser. No. 208,906 11 Ciaims. (Cl. 62-345) This invention relates to apparatus for making articles of ice and pertains more particularly to apparatus for making frangible targets suitable for use in conjunction with trap shooting.

The targets used in trap shooting are conventionally made of clay `or other suitable frangibie material and even though such material be inexpensive, the same does nevertheless constitute some degree of expense. It is of primary concern in connection with the present invention to provide apparatus for making target projectiles which are of substantially no expense and, to this end, it is a main objective of this invention to provide a machine for making target projectiles of ice. Aside from the cost factor above mentioned, certain other advantages accrue to the use of target projectiles for the purposes specified which yare made of ice. For example, conventional targets give rise in their use to a substantial amount of debris in the area of the target range and although the amount of debris from any one target may not be substantial, accumulations of such debris do nevertheless constitute a problem which must be dealt with. In accordance with the present invention, the projectiles made by the herein disclosed apparatus leave no debris which requires policing or cleaning up since the target debris being shards or particles of ice, will simply melt.

A further advantage of targets made with the instant invention resides in the fact that an infinitel variety of colors may be imparted thereto by the simple expedient `of introducing suitable coloring or dye material into the water which is used .to form the ice projectiles. Furthermore, it also becomes an easy matter to introduce variou-s other substances and materials into the water so as to render the targets phosphoresen-t, iluorescent or -lumi- Still another object of this invention resides in improvements in apparatus for producing molded articles in general wherein female die members kare so constructed and arranged as to automatically effect stripping and expulsion of the molded articles therefrom subsequent to their formation.

Another object of lthis invention resides Vin the arrangement of a pair of endless conveyor means in which such conveyor means are so interrelated xand disposed positionally with respect to each other as to cause periodic interengagement of m-ale and female die members oarried by such conveyor means.

Other objects and advantages of the invention will appear from the description hereinbelcw and Ithe accom- 'panying drawings wherein:

Referring now more particularly to FIG. l, reference character 10 indicates in general an insulated cabinet which may take any form desired and within which there is provided a compartment 12, likewise insulated, both of which insulated components are of substantial horizontal extent for purpose which will be presently ascertained. The invention also includes first and second endless conveyor means indicated generally by reference characters 14 and 16, which conveyor means are disposed in partial overlapping relationship in 1a manner presently more particularly set forth. The upper or first conveyor 14 is provided with guide means disposed in horizontally spaced relationship which may :take the form of idler sprockets 18 at one end of such conveyor means and driven sprockets 20 at the opposite end of such means. FIG. 2 illustrates the mounting for such sprocket means and, was shown therein, it will be appreciated that the idler sprockets 18 are mounted upon a common shaft 22 suitably journaled as by pillow blocks or brackets 24 and 26 so that the shaft 22 is disposed in horizontal transversely extending attitude, the brackets 24 and 26 being suitably tafiixed to a support plate member 28. The driven sprockets 219 are mounted in a similiar fashion upon a common shaft 30 which also is provided with a drive pinion 32 by means of which rotation is imparted to the shaft 30 to drive the conveyor means 14. The conveyor itself may comprise -a pair of endless chains 34 and 36, see particularly FIG. 2, which are bridged Iand interconnected by a series of longitudinally spaced male die members indicated generally by reference character 38.

As can be seen in FIG. 2, .each of the members 38 includes a mounting means in the form of a transverse plate 4d having upstanding ears 42 and 44 at its opposite ends which are pivotally attached to the links of the chains 34- and 36. Preferably, this pivotal connection of the ears 42 and 44 is achieved by extending appropriate pins which form pivotal interconnection between adjacent links of the chain. The strips orplate also mount upstanding bracket ears 46 and 48 arranged in pairs as is shown and rotatably supporting therebetween roller members 50 and 52 by means of suitable journal pins 54 substantially as is shown. These rollers 50 and 52 are adapted to engage. the under surface of the support plate 28 which, thereby, acts also as a guide member, the purpose of which will be more clearly apparent hereinafter.' The strips or plates 40 in each case are suitably attached to the body members 56 which constitute the male die member proper. This body 56 is shown more clearly in FIG.

8 of the drawing whereinrit will be seen tha-t the body is provided with a hollow interior 58 and is provided with a stepped lower surface as indicated by reference character 60, one of the steps 62 defining a downwardly facing annular shoulder for seating engagement upon the body of the female die member 64` associated therewith.

The endless conveying mechanism 16 is constructed in somewhat similar fashion to the conveyor mechanism 14 in that it includes a pair of spaced, parallel endless chain members 66 and 68, see particularly FIG. 5 which are bridged or interconnected by the female die members which, as previously described, are indicated generally by the reference character 64. The means of attaching each of the female die members 64 to the chains 66 and 63 is through the medium of a pair of attaching means which are spaced longitudinally along the links of the chain. As is shown in -FIG. 6, each of such attaching means includes a transverse plate member 7i) provided with depending7 ears '72 and v74- which, like the ears 42 and 44 of the male die members, are attached to the corresponding chains 66 and 68. The plates 70 proper are in turn rigidly affixed to the main body portions '76 of the female die members by means of suitable fastening elements such as bolts 78 as illustrated. Naturally, other suitable attaching means such as bonding or the like may be utilized if desired.

The female die member in each case is provided with a stepped concavity 80, see particularly FIG. 8, and is also provided with a flat upper surface 82 providing a seat for the shoulder 62 of the male die member so that interengagement of these component parts may be achieved in the fashion indicated in FIG. 8. Underlying the upper flight of the conveyor mechanism 16 is a support and guide plate 34 whose function and purpose is similar to the plate 28 previously described in conjunction with the conveying mechanism 14. The supporting plates 7f3 of the female die members also carry brackets 86 and 88, see FIG'. 6, rotatably supporting the rollers 90 which bear against the upper surface of the plate 84. Thus, the plates 28 and 841 together with the roller means of the associated male and female die members provide for proper interengagement between the male and female die members so that the proper die cavity is formed therebetween which, being filled with a quantity of water 94 as is shown in FIG. 8, may form the target projectile.

As can be seen more clearly in FIG. l, the compartment 12 is. provided with suitable refrigerating means such as the coils or refrigerating pipes 100 located directly beneath the plate 84 so that in the region of the interengaged male and female die members indicated by reference character 102 in FIG.. l, a substantial degree of refrigeration will be effected. It will also` be seen from FIG. l that the underlying endless conveying means 16 is of materially greater length than the conveying means 14 and the two are so disposed in stacked relationship to each other that the lower flight 104 of the upper conveyor mechanism 14g is disposed parallel to the upper flight 106 of the lower conveyor means 1 6. A t the same time, the length of the conveying means 16 is sufficient to venable the location of the guide sprockets or means 108 and 116 within the confines of the insulated cabinet 1i) rather than the compartment 12 and suchl guide means are so disposed as to align the upper flight 106 to pass through the compartment 12, suitable end wall openings being provided in such compartment for this purpose. Each of such openings may be provided with a suitable flexible flap or cover 112 or 114 which will normally close at least a substantial extent of such openings to prevent eX- cessive loss of heat into the compartment 12. Because the water is introduced into the female die members in the region of the cabinet 10, it is preferred that the ternperature thereof remain somewhat above the freezing point and yet, at the same time, it is desirable that the ambient temperature thereof be sufficiently low as to lend good efficiency to the entire apparatus. The ambient temperature of the compartment 12 is, on the other hand,

substantially below freezing and to such an extent as to cause rapid freezing of the articles being made so that the machine may be run at an efficient speed. To further enhance the efiiciency of the device, it is preferred that the male die bodies 66 be formed of material such as aluminum for good and efficient conductivity, as will be well understood.

The aforementioned guide means 10S and 110 for the lower conveyor means 16 are similar to the previously described guide means 1% and 20 for the upper conveyor. That is to say, each comprises a pair of sprocket wheels engaged with the respective chains 66 and 68 and affixed to a common shaft in each case, such shafts being indicated by reference characters 116 and 118. The driven guide means 198 may be utilized for effecting a drive to an article discharging conveyor indicated generally by the reference character 12o and, for this purpose, a suitable pulley may be affixed to the shaft 116 outboard of the sprockets fixed thereto and a belt 122 may be utilized to effect drive to the conveyor shaft 124. The conveyor shaft 124 may be provided with a suitable roller or the like 126 training one end of an endless conveyor belt 123 thereover, a suitable idler roller 130 being provided eX- teriorly of the cabinet 10 in the fashion shown to convey finished articles such as those indicated by reference character 132 exteriorly of the assembly.

The other guide means is utilized for driving purposes and, to this end, a suitable electric motor` or the like 134 may be mounlted as shown and may be provided with a belt drive 136 to the shaft 113. The shaft 118 also carries a drive sprocket or gear 138 which, through the medium of chainV 141B effects drive to a countershaft 142 having a gear 144 mounted thereon. This latter gear 144 is in mesh with the previously mentioned gear 32 affixed to the drive shaft 3@ of the upper conveyor means 14. Thus, it will be appreciated that the two conveyor means 141 and 16 are driven in unison and lin predetermined relationships to each other Iso that the interdigitation between the male and female die members thereof takes place sequentially as will be clear from a study of FIG. l.

As previously mentioned, the male die members 38 are pivotally attached'to their endless chain means so that these members may flop around relatively freely and this relationship permitsv of easier interengagement or interdigitation between the male and female die members'since the male die members, being so mounted, arerpermitted to pivot and therefore align themselves properly with the corresponding female die members. This action also permits the disengagement between male and female die members to be effected without damaging the finished articles. That is to say, the withdrawal of the male die members from the solidified finished target which remains within the female die members is more easily effected by virtue of the pivotal mounting of the male die members.

At the same time an additional feature of the present invention resides in the specific mounting ofthe female die members as previously described in conjunction with FIG. 6. As was described, each of lthe female die members is attached to its respective chains at longitudinally spaced points along these chalins and there is no rigid element intervening between these attachment means, the bodies of theV female die members being made of flexible material such as rubber or the like. Thus, as can be seen in FIG. 1, at the discharge end of the mechanism and particularly the conveyor 16, the guide means 1118 will deform the' main bodies of the female die members and effect a stripping action so that the finished articles may readily fall onto the discharge conveyor belt 128. This relationship is shown more clearly in FIG. 7 of the drawing wherein, as shown, the flexible or rubber body 1410 of the female die member will be seen to have been deformed by virtue of the chains passing over the guide means 108 so that the spaced apart attaching members 142 and 144 for the body 140 will tend to deform the same in the fashion shown so that the die cavity 146 thereof will be enlarged by stretching and deformation of the body 149 to strip and readily expel the finished target 148 therefrom.

As can be seen in FIG. l, water introducing means indicated generally by the reference character 150 is employed within the contines of the cabinet exteriorly of the compartment 12 and in such fashion as to introduce water into the female die members just prior to their entry into the contines of the compartment 12. Such means 150 takes essentially the form of a valve body member 152 having flexible supply connections 154 and 156 leading thereto from a suitable external source and having a discharge conduit 158 leading therefrom substantially as is shown. One of the supply connections extends to a suitable source of water while the other may extend to a suitable source of dye material, fluorescent or phosphorescent material, or the like, for the purpose of imparting desired optically discernible characteristics. When the system is so used, the Valve 152 would of course have suitable mixing characteristics. As can be seen more clearly in FIG. 5, the valve body 152 is movably carried by means of a pair of arm members 160 and 162 which are pivotally mounted at their lower ends, as by means of suitable members 164 and 166, to the frame of the machine and which extend upwardly from such pivotal connections in straddling relationship to the chains 66 and 68 to pass above the upper flight of the conveying means 16 and terminate in upstanding arm portions 170 and 172 pivotally mounting a guide block 174 therebetween. The guide block 174 is carried slidably along a bar member 176 and is normally urged to a retracted position by means of a compression spring 188. However, the carrying means for the valve body 152 is swingable through an arc as is indicated by the arrow 182 in FIG. l.

The valve body 152 may be either rigidly fastened to the guide block 174 or carried between the upper end portions of the arms 160 and 162, the former type of connection being preferred, as -is seen in FIG. 3 wherein the guide block 174 and the body 152 are joined as by the web or interconnecting means 19t). FIG. 3 also illustrates the means for initially positioning the valve body 152 which may simply take the form of suitable stop pins 192 mounted on the frame 194 of the machine and projecting laterally outwardly therefrom to provide stop surfaces against which the arms 166 and 162, as the case may be, abut in a desired extreme right-hand arcuate position of the members 152 and 174. The valve body 152 may incorporate any suitable electrically controlled valve mechanism of the one-shot type adjustable to discharge, through the nozzle or conduit 158 a predetermined quantity of water each time the electrical mechanism is actuated. To effect the energization of such valve mechanism, the frame 194 carries a suitablemicroswitch, not

shown, having an actuator in the form of a pivoted arm 200 carrying a roller 202, see particularly FIG. 4, which is so disposed as to be engaged by one or the other of the arms 169 and 162 as the same are arcuately moved as indicatedV between full and dotted lines in FIG. 3. Consequently, every time the arms are swung, the oneshot valve mechanism is operated to introduce the requisite quantity of uid into the registered female die member such as that indicated by reference character 264 in FIG. 3. In order `to cause movement of the arms 160 and 162, the chains 66 and 68 of the lower conveyor means 16 are provided at longitudinally spaced points thereon with laterally outwardly projecting link pins 206, see particularly FIG. 4, which are adapted to strike against abutment members 203 fixed to the inner sides of the arms 16d and 162. The abutment means or lingers 20S are of such dimensions as to normally be placed in the path of movement of the pins 206 and, when engaged thereby, cause the arms 16%) and 162 to be carried along with the chains until such point as the pins 206 ride over the upper ends of the ngers 208, thereby releasing the arms and permitting them to swing to their normal posian insulated cabinet,

tion against the stops 192. Whereas the compression spring 180 assures a quick return of the arms 160 and 162 and consequently of the valve body 152, auxiliary springs 210 connected between the arms and 162 and suitable brackets 212 provided on the frame of the machine assure proper engagement of the arms 160 and 162 against their stops 192, it not being necessary in the full line position of the elements as shown in FIG. 3 that the compression spning be exerting any force whatsoever for returning the arms 160 and 162. As has been stated, the main purpose of the spring 180 is to assure a rapid return action of the valve body 152. Thus, the mechanism may be operated in a relatively fast rate of speed, limited only by the rapidity with which the introduced water can be frozen within the compartment 12 which, as a matter of actual fact, lcan be accomplished relatively quickly particularly in view of the fact that the projectiles, as are shown in FIGS. 9 and 10, are of relatively thin section and thus can be effected to a frozen condition in relatively short order. Thus, the valve block 152 as it moves along under the action of thearms 160 and 162, discharges the requisite quantity of water into the mold cavities of the female die members and then is returned with a rapid action forintroduction of the next shot of material into the next succeeding female die member.

Even though the bodies of the female die members are exible and/ or resilient, the specific mounting means hereinbefore inbefore specified assures that they will be in proper shape and position when the interdigitation between male and female die members takes place. This is further enhanced by the guide rollers associated with the female die members and of course the same obtains for the male die members. That .is to say, insofar as the male die members are concerned, .they will be properly oriented in vertical height at least by their associated rollers bearing aginst the plate 28. It is to be noted thatl the deformation of the female die members takes place after the guide rollers thereon pass from engagement with the plate 84, thereby obviating an accurate disposition of an arcuate portion of such plate 84 as would otherwise be necessary in order to avoid undue stresses on the chains 66 and 68 and in order to avoid any tendency to derail such chains from the guide means 108. It will be appreciated, further, that the targets as indicated by reference character 214 in FIGS. 9 and 10 may be of any desired shape or configuration, but it is preferred that in any case they are of relatively thin section so as to enable the refrigerating means to most rapidly and efficiently effect a freezing action and thus complete the article, thereby permitting the conveyors to be run at a relatively high speed. Furthermore, it is also preferred that the entire assembly as hereinbefore described be of an integral unitary structure, including a Vsuitable compressor 216 and condenser 218` for the refrigerating means and any suitable associated mechanism therefor. In this fashion, the

entire assemblage may be placed at any desired point as for example immediately adjacent the target projectile launching means if so desired.` Of course, the mechanism as above described may also be placed rin a remote poirt and the finished targets simply refrigerated until use It is to be understood that certain changes` and modifications as illustrated and described may be made without departing from the spirit of the invention or the scope of the following claims.
